Floor joist cross bacing


How far apart should cross bracing be on floor joists? Currently we are using the nail-less cross bracing, was thinking about adding more to strengthen up our floor.

Use blocking instead.

Interested in this as well.

I have heard that blocking can squeak. Any comments?

As for distance between I was planning for every 2 feet. Is that overkill?

Most homes are built with joists that are 16 inches center to center, so the space between them is 14.5 inches. Residential building code requires the use of cross bracing or blocking for floor joists exceeding 2 inches by 12 inches. But for cross bracing, you can add the braces at 8-foot intervals.

Continue with the X bracing. It's been known since back before Caesar the triangle excels in construction.

Yes the space between joists is 14.5 in. But I am not sure I follow what you mean when you say "exceeding 2 inches by 12 inches"
